DEEP WELL PUMP COLUMN. APPLlcATloN FILE'DNov. 24, 1914.

where, when operating and giving the quantity called for, it will be submerged about up to the point of the diaphragm cup leather 12, f'. c. just submerged, as thereby there will' never be any trouble during the time of operation. The pump when not in operation will be submerged, as the water accumulating will pass through and over same. There will in that instance be no pressure against the inner side ofthe diaphragm 12 because everything will be neutralized; but the moment the pump starts, the column of water above the diaphragm will immediately rise,

while the water below will have a tendency.

to drop, thus creating sufficient pressure on the inner upper side of the diaphragm to force this against the well casing and form a joint sufficiently tight to support the discharging water column. p

Thus it can be seen that the flexible diahragm 12, conveniently illustrated as a cup lieather construction because of itsl simplicity and practicability, constitutes an automatically expansible partition carried by the pump, coperating with the well casing to divide the Well into upper and lower -Colnpartments, the upper of. which constitutes the discharge column of the pump, thereby eliminating 'the use of a separate pipe forthe discharging water and consequently reducing the cost of manufacture and installation.

This construction furthermore produces.

' pump.

The protective tubing 4 is not designed or intended to exclude the water from around the shaft, but merely to protect the latter from interference by foreign matter in the well and provide an easy method of suspension and lubrication. Accordingly the tubing, in addition to being open at the top, is open to the water in the well at the bottom through ports 16 and 17 in the pump case; the strainer 18 serving to pre'- vent the entry of grit. and other foreign matter into the tubing 4 and shaft bearings. Consequently the water in the tube is maintained at allV times at the same level as the water in the well when the water is above the diaphragm 12.

20 is a port extending radially through the pump case as seen in Fig. 2, connectingthe chamber 21 between the gland 22 and "well. The purpose of this port 20 is to Vent any water that would otherwise be forced A by the action of the impeller `up past the gland and bearing into the tubing 4, with the result under some conditions, of displacing all the oil in the inner tube and also cutting the bearing 23.4 It is to be understood that in the operation of these pumps the impeller exerts a considerable upward' pressure dependent upon the head pumped against tending to force water along the pump shaft 3 and up through the tube 4 and bearings 6 in which the shaft turns. This pressure unless controlled, or taken care of, is sometimes sufficient to fill the inner tube 4, particularly if this tube is closed off at the bot! aov It also prevents sand-and grit from geti ting'into the bearing 23 and cutting it out. This is quite an important feature.

rllhe spring 24 in chamber 21 is designed packing 22.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1.; ln a deep well pump, thel combination l of an outer casing, a line shaft, a tube surrounding and spaced from the shaft, an impeller secured to the shaft, a casing inclosing the impeller and supported by the tube, said shaft and tube together with the impeller and its casing being'suspended from above entirely independent of the outer casing, whereby the tube and shaft are placed in tension and independent of the casing, and a diaphragm member connected with theautomatically to take up any Wear of the` pump and coacting with the casing to center the pump within the, casing.

2. In a deep well pump, the combination of an outer casing, a line shaft. a tube surf rounding and spaced from the shaft, an impeller secured to the shaft, a casing inclosing the impeller and supported by the tube, said shaft and tube, together with the impeller and its casing being suspended from above entirely independent of the' outer casing, whereby the tension and independent of the casing, and

a diaphragm member connected with theV pump and coa'cting with the casing to form with the casing a water discharge forthe pump.

3. In a deep well pump, the combination' of an outer casing, a line shaft, a tube surrounding and spaced from the shaft, an 1mpeller secured to the shaft, a casing mclosmg the impeller and supportedby the tube, sai

shaft and tube, together with the impeller and its casing being suspended from above entirely independent of the outer casing,

tube and shaft are p laced in p whereby the tube and shaft are placed in tension y.independently ofl the outer easing and a diaphragm member connected with the pump casing and coacting with the outer casing to center the pump within said Outer casing.

4. In a deep well pump, the combination of an outer casing, a. line shaft. a tube surrounding and spaced from the shaft, an im* peller secured to the shaft, ay casing inclosing the impeller and supported by the tube, said shaft and tube, together with the impeller and its casing being suspended from above entirely independent of the outer casing whereby the tube and shaft are placed in tension independently of the outer easing, and a diaphragm member connected with the pump casing and coacting with the outer casing to form with said outer easing a water discharge for the pump.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
